Losing connection

[RipperT]

I have an odd problem. I have 3 XP Pro machines connected to a broadband
modem thru a router. One of the machines loses it 's connection after
leaving it sit without use for a long while. The only power save feature
enabled is the monitor truns off after an hour. The computer doesn't go into
hibernation or standby. Connection status shows good connectivity at 100
mbps, but I cannot load any pages from the web or retrieve any email. I've
disabled, enabled and repaired the connection; that doesn't work. I've tried
logging off the computer and back on; that doesn't work. Rebooting is the
only thing that works. How can I find out what's causing this?

Many thanx,

Ripper

When you say "the only power save feature enabled..." does that mean you
checked Power Management on the network adapter also? If you didn't,
then please go to Control Panel>System>Hardware>Device Manager. Expand
the network adapters category and find your ethernet adapter.
Double-click it to open its Properties and then click on the Power
Management tab. Uncheck "allow Windows to turn off this device when not
in use".

So when this one computer loses connectivity, the others have no problem? What
differences are there between this one and the others?

Start by comparing "ipconfig /all" with the 3 computers.

And verify where connectivity is being lost, using PingPlotter.

Malke,

Many thanx. The selection was indeed checked and I unchecked it. Time will
tell. What controls the amount of time that will elapse before the computer
shuts down the device to save power?

Thanx again,

Rip

Well, that didn't work. The computer still loses it's connection after
sitting 12 hours. I get a DNS error in web pages and the email times out.
The only fix is to re-boot, and in answer to Chucks question, no, the other
two machines, one wired, one wireless, have no problems.

Thanks again,

Rip
